Locked6 lessons remaining to earn this badge.
Owning a stock means owning a business, and businesses can be read. This level teaches you to walk through the three core financial statements, recognise what durable quality looks like, and understand how price and risk fit together — all without ever telling you what to buy.
What you'll learn
- Explain what a share of stock actually represents
- Read an income statement and know what each margin tells you
- Read a balance sheet and judge financial strength versus fragility
- Distinguish reported earnings from actual cash generation
- Weigh valuation and different types of risk before judging whether a price is reasonable
- 2.1
What Owning a Stock Means
A stock is a unit of ownership in a real business, not a betting ticket on a price.

Understanding the Balance Sheet
The balance sheet is a snapshot of what a company owns, what it owes and what is left for shareholders.
8 min - 2.4

Cash flow measures the actual cash a business generates and spends, which can differ from its reported earnings.

Worked case · Hypothetical example
Reading one fictional company's three statements
Skill: Reconciling income statement, balance sheet and cash flow; EPS and margin
Fictional Ridgeway Tools Inc., fiscal year 2025 (all figures invented).
| Revenue | $200m |
|---|---|
| Net income | $20m |
| Shares outstanding | 10m |
| Cash, start → end of year | $30m → $38m |
| Operating cash flow | $26m |
| Capital spending | $12m |
| Dividends paid | $6m |
Worked through
- EPS: $20m ÷ 10m shares = $2.00 per share.
- Net margin: $20m ÷ $200m = 10%.
- Reconcile cash: $26m − $12m − $6m = +$8m, matching the balance sheet change $30m → $38m.
- Profit vs cash: Net income ($20m) and operating cash flow ($26m) differ because of non-cash items such as depreciation and working capital.
Limitation: One year says little about a trend; EPS also changes when the share count changes (for example, buybacks).
Your turn
Check yourself against the rubric
- EPS = $2.20; margin = 11%
- Mentions share-count change (dilution) or cash-vs-profit difference
- Treats one year as limited evidence
